PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z))
IUPAC 名称
[(2S)-3-({[(2R)-2-[(7Z,10Z,13Z,16Z)-docosa-7,10,13,16-tetraenoyloxy]-3-[(6Z,9Z,12Z)-octadeca-6,9,12-trienoyloxy]propoxy](hydroxy)phosphoryl}oxy)-2-hydroxypropoxy]phosphonic acid
描述
PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z)) belongs to the class of glycerophosphoglycerophosphates, also called phosphatidylglycerophosphates (PGPs). These lipids contain a common glycerophosphate skeleton linked to at least one fatty acyl chain and a glycero-3-phosphate moiety. As is the case with diacylglycerols, phosphatidylglycerophosphates can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PGP(18:3(6Z,9Z,12Z)/22:4(7Z,10Z,13Z,16Z)), in particular, consists of one 6Z,9Z,12Z-octadecatrienoyl chain to the C-1 atom, and one 7Z,10Z,13Z,16Z-docosatetraenoyl to the C-2 atom. In E. coli, PGPs can be found in the cytoplasmic membrane. The are synthesized by the addition of glycerol 3-phosphate to a CDP-diacylglycerol. In turn, PGPs are dephosphorylated to Phosphatidylglycerols (PGs) by the enzyme Phosphatidylglycerophosphatase.
